Simsima for Japan FAQ
Does Simsima offer unlimited data eSIM for Japan?
No, Simsima does not provide a truly unlimited high‑speed data plan for Japan. The plans that carry “Unlimited” in their name offer a fixed daily allowance of 3 GB; once that daily limit is met the speed is throttled to 1000 kbps. Therefore the name should be understood as “unlimited” in a technical sense of continuous service, not in a data‑cap‑free sense.
For travelers who need large amounts of data, Simsima offers fixed‑cap alternatives that may be more cost‑effective. Examples include a 100 GB plan valid for 180 days, a 60 GB plan valid for 125 days, a 50 GB plan valid for 90 days, as well as 50 GB and 20 GB plans for 30 days. These plans give substantial high‑speed data without the post‑cap speed reduction.
Does Simsima offer Japan eSIM with phone number and SMS?
Simsima does not provide a Japan eSIM that includes a phone number or SMS capability. All Simsima plans for Japan are data‑only, so a separate phone number is not available with these plans. Travelers can still use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.
How many data plans does Simsima offer for Japan?
Simsima offers 31 single‑country data plans for Japan and 24 multi‑country plans that include Japan. The available plans lie in a price range from roughly $3.38 to $452.76 and offer data caps between 500 MB and 100 GB, with validity lengths ranging from 3 to 365 days. Some plans provide a fixed data amount for the entire validity period, while others impose a daily data cap, allowing different usage patterns for travelers.
